Method for preparing filling material for incendiary bombs and flares



Patented MEOB FOR PREPARING I INC v you IlClaim.

My invention relates to improvements in the manufacture or filling material for incendiary bombs and flares for military and other indus- Y trial uses.

The principal ingredients of my bomb are magnesium particles and paper pulp made from wood fiber or other combustibles.

The manufacture oi the filling for an incendiary bomb or flare is preferably as follows:

Ma nesium in the form of small particles of 10 approximately 500 microns in size is mixed with wood pulp and water in such a proportion that the' particles of magnesium are disseminated I throughout the mass.

The well agitated mixture of pulp and magnesium particles is filtered through a continuous suction filter, the pulp impregnated with mag nesium particles forming a filter cake in the form of a ribbon. This ribbon is dried and is used in various forms as a filler in the bomb. It can be broken in small pieces or used in rolls. This material burns with an intense heat. The particles of magnesium are close enough together Ernest F. Fisher,

in the pulp to prclomr combustion without burning too rapidly. The pulp fibres term a porous medium through which the magnesium particles are distributed. the magnesium particles being separated from each other by a slower burnin: combustible, and the requisite oxygen for combustion'.

My incendiary bomb filling requires a relative- 1y small amount of magnesium and large Doweriul combs or great incendiary power can be manufactured with only a few cents worth of magnesium. This material is safe to handle and to store.

I claim:

A method or making filling for incendiary bombs consisting of pulping pa r and mixing magnesium dust with said pulp and water; asitating this mixture and filtering said mixture to form a uniformly flat sheet or ribbon and finally drying said sheet or ribbon tor use in an incendiary bomb.
